Apache PTT Relay

[Glen Zook]

That is why I suggested running the relay on DC.
Switching DC shouldn't be any more of a "hum"
generator than switching the relay through a tube.

However, there are some of the older equipment that
actually use AC for the PTT relay!  Those units don't
seem to have any more "hum" than usual!  But, I
certainly would think twice before doing this!

Running AC down the mic cable seems to me to be a real
